Description: Confidentiality breach refers to the unauthorized disclosure of confidential information, which can have serious consequences for individuals and organizations. This concept is fundamental in the realm of data protection and privacy, as it involves the exposure of sensitive data that should remain protected. Breaches of confidentiality can occur in various ways, including unauthorized access to databases, information leaks through digital or physical means, and misuse of personal data. The main characteristics of this phenomenon include the lack of consent from the information owner, the potential for harm to the reputation or security of affected individuals, and the potential legal liability for entities handling such information. The relevance of confidentiality breaches has grown in the digital age, where the amount of data generated and stored is immense, and threats to information security are increasingly sophisticated. Therefore, it is crucial for organizations to implement adequate measures to protect data confidentiality and avoid situations that could compromise individuals’ privacy.
